Abstract
A damper disc has side plates adapted to be connected to a torque input part so as to coaxially rotate therewith. A hub is connected to a torque output part and rotates coaxially to the side plates. A sub-plate is adapted to torsionally turn with respect to the side plates and the hub and is disposed coaxially thereto. A first spring mechanism circumferentially connects the sub-plate to the hub. A second spring mechanism circumferentially connects the side plates to the sub-plate. The spring mechanisms include a plurality of torsion springs disposed in series and spring seat units interposed between the adjacent springs. These spring seat units include a spring seat to which one of the springs is seated, a second spring seat to which another one of these springs is seated and a connecting means for connecting both spring seats together so that both spring seats can change their orientation with respect to the radial direction of the disc.
